Preheat oven to 400 degrees.
Put the tofu and pepperoni slices in the oven for a few minutes to warm them while you chop the veggies up.
Toast bread.
Mash avocado. Add lime, salt and pepper to taste.
Spread avocado on the toast, if you put olives on the sandwich, place them on top of avocado as it will help hold them.
